Hi Andrea
I'd like to inform you that as per information that can be found on this page:
http://www.mysql.com/support/supportedplatforms/workbench.html
we no longer support 32bit linux systems, yet I'll try to give you some help.
To get it done, it should be enough to get almost all packages from the system repository. The following list should be enough (you can copy paste it):
yum install cmake tinyxml tinyxml-devel gcc-c++ libzip libzip-devel gtkmm24-devel swig mysql-community-devel mysql-community-client libxml2-devel gdal-devel unixODBC-devel pcre-devel libgnome-keyring-devel libuuid-devel vsqlite++-devel ctemplate-devel autoconf automake libtool boost-devel
after installing packages, you'll have to download
mysql-connector-c++-1.1.6-linux-glibc2.5-x86-32bit.rpm
from
http://dev.mysql.com/downloads/connector/cpp/ located in Linux-Generic.
and once installed, you should be able to build WB.
Please let us know if you find any problems.
